Definitions
- the invention relates to a method for feeding a new fiber or the like into a spray head for coating or covering the fiber when a first fiber currently in the spray head is coming to an end, and to a device for inserting or feeding a new fiber or the like into a spray head for coating or covering the fiber, with a feed device for the fiber in the spray head.
- the invention relates to the feeding or tracking of fibers or cores in a spray head, the invention not only with individual fibers or cores, but also with one or more fibers with secondary coating, several loose fibers, fiber bundles, stranded fibers and several Strands of fiber bundles or stranded fibers or veins can be used.
- the fibers or cores can be made from a wide variety of materials, for example glass or plastic for optical fibers or copper for electrical lines. If reference is made to fibers below, all the aforementioned products are meant.
- For coating or covering fibers they are passed through a spray head in which the coating or covering is applied to the fibers. Since the fibers can only be provided in a finite length on rolls or the like and guided into the spray head, at the end of a fiber there is a need to either interrupt the process of wrapping or coating, insert a new fiber into the spray head and the Then start the process again or accept that in the case of an uninterrupted process of wrapping or coating, a relatively long distance is created as a reject until after the end of a first fiber, a second fiber is reintroduced into the spray head.
- the invention is therefore based on the object, a method and to provide a device which shortens the time to add a new fiber after the end of a previous fiber.
- the invention is essentially based on the fact that while a first fiber is still running through the spray head, a new fiber is already provided in a feed device which is positioned next to the first or old fiber. Because the second fiber is provided immediately in front of or next to the spray head, the change from the first to the second fiber can be carried out very quickly, as a result of which the loss of material or rejects in the changeover area from the first to the second fiber are kept relatively low in an uninterrupted process can be.
- two, preferably identical, feed devices are provided, namely a first one which is assigned to the fiber currently passing through the spray head and a second one which is assigned to the fiber provided, then as soon as the end of the first fiber is reached, the first feed device is moved away from the area in front of the spray head and the second feed device is simultaneously positioned in front of the spray head, whereupon the second fiber provided is immediately introduced into the spray head and accelerated until the intended processing or line speed of the fiber is reached again ,
- the first and the second feed device are moved simultaneously. This is preferably done in that both feed devices are mounted on a frame which can be displaced or swiveled in by the drive at a right angle or transversely to the direction of insertion of the fiber into the spray head.
- a single fiber draw would suffice to get the fiber subtract from the fiber storage and convey into the spray head. It is preferred within the scope of the invention, however, if the new fiber is accelerated by a second fiber take-off arranged in front of the spray head and that the conveying speed of a first fiber take-off arranged in the direction of movement of the fiber before the second fiber take-off as a function of the length of the fiber contained in a fiber storage arranged between the first and the second fiber draw is present, is controlled. In this way, the acceleration of the fiber when introducing the fiber or feeding a new fiber into the spray head can be carried out optimally, ie in a very short time.
- FIG. 1 shows a side view of a schematic representation of an embodiment of the invention and FIG. 2 shows a top view of the device as shown in FIG. 1.
- a single fiber 1 is shown, which comes from a fiber storage, not shown in the drawing, for example a drum, coming in ' Direction of arrow 2 is guided to a spray head 3 in which the fiber is coated or coated, which is well known in the prior art, so that the spray head 3 is not described in detail.
- the fiber 1 is guided in the direction of movement 2 coming from the fiber storage through a pre-wetting unit 4, a first fiber draw 5, a fiber storage 6 with a wire hanger 7, a second fiber draw 8 and a guide tube 9 into the spray head 3.
- the pre-wetting unit does not have to be provided or can also be arranged at another location, for example between the first fiber draw 5 and the dancer 7 or the dancer 7 and the second fiber draw 8. In normal operation, ie when the fiber 1 with normal operation or.
- the fiber draw-offs 5 and 8 and the fiber storage 6 are usually only closed or active when a new fiber 1 is introduced or tracked into the spray head in order to accelerate the fiber 1 up to the operating or line speed.
- an operating mode is also conceivable in which the fiber draw 5 is always closed or active.
- FIG. 2 In order to be able to insert a new fiber 1 into the spray head 3 or to feed a new fiber 1 into the spray head 3 in the shortest possible time when a preceding fiber 1 ends, as shown in FIG. 2, there are two essentially identical feeders 10, 10 "are mounted side by side or one above the other on a mounting plate or a mounting frame 11.
- the mounting frame 11 is displaceable transversely to the direction of movement of the fiber 1, as indicated by the double arrow 12, by one time the first feeder 10 and another time to be able to position the second feed device 10 'in front of the spray head 3.
- a fiber 1 ' is being processed at normal operating speed, so that, as mentioned, the fiber deductions 5' and 8 "and the fiber storage 6 'are deactivated.
- the feed device which is fastened to the mounting frame 11 next to the feed device 10' 10 is in the waiting position in the situation shown in FIG. 1, in which a fiber 1 is prepared for feeding into the spray head 3, that is to say that the beginning 13 of the fiber 1 is positioned at the mouth 14 of the guide tube 9.
- the guide tube 9 'with the fiber draw-off 8' is withdrawn and the mounting frame 11 is displaced (in FIG. 2 upwards in the image plane), so that the feed device 10 with the guide tube 9 is then positioned in front of the spray head 3, whereupon the guide tube 9 moves forward a short distance in the direction of movement of the fiber 1 and into the inlet area 15 of the spray head 3 is moved.
- the guide tubes 9, 9 ' can also be divided in the longitudinal direction.
- the fiber draw-offs 5 and 8 begin to work essentially simultaneously, so that the new fiber 1 is introduced into the spray head 3 with its start 13.
- the synchronization of the fiber draws 5 and 8 takes place in such a way that the fiber drawdown 8 first specifies the speed or acceleration of the fiber 1 and the fiber drawdown 5 is regulated with the aid of the wire bracket dancer 7 such that sufficient fiber 1 is always present in the fiber store 6.
- the coated or coated fiber is drawn more and more from a trigger arranged after the spray head 3 (not shown in the drawings) over the covering material, for example a tube covering the fiber, whereupon the freewheel on the fiber trigger 8 becomes active.
- the wire iron dancer 7 now causes the fiber withdrawal 5 to accelerate further.
- a single feed device 10 ' which in turn can consist of a first fiber draw 5', a fiber storage 6 ', a second fiber draw 8' and a guide tube 9 '.
- a wetting unit 4 ' would then have to be arranged at a different location, if one is required at all.
- the feed device can be deactivated in any case during operation, it can be moved laterally or upwards or downwards away from the current fiber, so that it can then assume the position that the feed device 10 assumed in FIG. 2 becomes. There would then be no feed device in the area of the current or first fiber 1 '.
- a new or second fiber 1 can then be introduced and prepared in the feed device 10 'arranged next to the fiber 1' and the feed device 10 'would then, when the first fiber 1' comes to an end, again in the feed area in front of the spray head 3 are moved, whereupon the prepared fiber 1 can be introduced into the spray head.
- the feed device 10 ' can then be moved away again from the region of the fiber 1'. In this way, it is an operation according to the invention of the direction also possible if only a single feed device 10 'is provided.
- the invention can of course not only be used to track a fiber when a fiber runs out during operation, but also to insert a fiber for the first time at the start of operation.
